<p>A first memory area and a second memory area are provided. The first (second) memory area is provided with at least one first (second) memory module group, each of the first (second) memory module group is provided with at least one first (second) memory module, and each of the first (second) memory module is provided with a plurality of memory chips. In the case in which an erroneous chip is in the first memory module, a first memory module group that is provided with the error chip is not managed as a memory module group that cannot be used even if there is a possibility that an error of the first data element is mis - corrected based on the error detecting code of the first kind. In the case in which an erroneous chip is in the second memory module, a second memory module group that is provided with the error chip is not managed as a memory module group that cannot be used in such a manner that an error of the second data element is not mis - corrected based on the error detecting code of the second kind.</p> |
